T cell 'tphom it may concern:

Be it. known that I, 'WILLiAM IHALEY,

a citizen of the United States, residing at Cir Knoxville, in the county of Knox and State .of Tennessee, have invented a new and use ful Improvement. in shoveling-Machines, of which the following is a specification, reference being had to the accompanying drawing.

My improvement relates particularly to machines for loading coal and other minerals in approximately horizontal inine workings and in storage places and for shoveling Qearth, sand, and gravel where excavations are being made, and elsewhere.

The present improvement is a modification of the shovel-actuating mechanism constituting a portion of a machine described in an application for LettersPatent of the United States, Serial No. 381,624, filed by me July 1, 1907, the machine described by said application comprising (1) a section which is, in effect, a low car having four wheels intended to rest upon light track rails; (2) an approximately horizontal, endless apron conveyer or carrier supported by said car; a jib crane section pivotally mounted upon said car and tiroj-ecting horizontally forward from the car; an end lessapron conveyer Ol CZIl'I'lOl mounted UPOH said jib section in proper position to discharge upon the first mentioned apron, in whatever position the jib section may stand; (5) a shovel or scoop supported .at the outer or free end 'of said jib section and so con trolled as to move forward with its nose 'upon the floor or ground and take a load,

lift the load and move it rearwardhnd di charge it upon the forward conveyor. lo

the machine of said application, a portionof the shovel turned or tilted rearward during the bodily rearward movement of the shovel, until said portion is inverted to such extent as to pour its contents upon said forward convcver. and such turnin of said said cog gearing.

Inasmuch as the present improvementrelates only to the shovel and the parts directlyfassociated therewith, it is deemed unnecessaryto illustrate and describe the entire machine.

In the accompanying drawings, Figure 1 is an upright longitudinal section of an apparatus embodying my improvement; Fig. 2 is a plan of the same apparatus, portions being broken away; F ig. 3 is a section on the line 33 of Figs. 1 and 2; Fig. dis asection on the line 4-4 of Fig. 1; Fig. 5 is a perspective of' the ffaming' upon which the shovel is supported; Fig. 6 is a side elevation of one of the cam plates used for controlling the movements of the shovel; Figs. 7 and 8 illustrate a modification.

Referring to said drawings, A, A are side rails or arms of a jib frame or any other frame by which the shovel and the shovel-actuating mechanism are supported.

At the right hand end of each of said side rails is secured a short standard, A having a horizontal transversebearing, A Said arms, A are joined to each other by transverse horizontal frame pieces, At, joined to said arms by bolts or rivets, A. To the arms, A, thus described is applied a supplemental shovel frame (Fig. 5) comprising two side pieces, A havingbetween their ends upright ears, A, in which are bearings, A, througl'i which extend bolts, A which bolts also extend through the bearings, A','

which have been described as being supported by the standards, A Said shovel frame side pieces, A extend downward from said ears and then toward each-other beneath the main arms until they meet each other. Said pieces, A, may bear against the lower faces of the side rails, A

On the right hand end of each shovel frame side piece, A, is a horizontal transverse bearing, A in whichrest the ends of a crank shaft, A, to which is applied one end of the shovel, B, as will be hereinafter described. Eachend of the crank shaft projects throu'gl'i the adjacent bearing, A and bears a sprocket Wheel, A, keyed to said shaft. Between said bearings, A and the ears, A", an upright cam plate, A 15 secured to each side piece, A. The lower edge of each of said cam plates overlaps the outer face of the adjacent side icce, A and is secured to the latter by bo ts or rivets, A. Along the inner face of each of said cam plates is a cam groove, A in which slidably rest the ends of a horizontal transverse bar, B 5 The ends of said bar are shown surrounded by. an anti-friction roller, B Said-bar, B supports the rear end of the shovel, as will be hereinafter described. Said cam plate, A, extends obliqiielyupward and toward the main portion of the jib-away from the crank shaft, A. Above about the middle of the'length of the groove,

A a groove, A begins on the inner face of said plate, and extends thence rearwardaway from the crank shaft, A, and forms the rear end of the groove, A The function of said groove, A, is to receive and change the course of a crank on the bar, B

-which supports the rear shovel section, B,

as will be nextdescribed,

A littlerearward of the nose of the shovel, B, are bearings, B in which rests the crank shaft, A. The shovel is composed of a forward section, B and a rear section, B".

The forward section has at each side a rearward extension, B terminating in a bearing, B9, loosely surrounding the bar, B so that-said forward section, B, is journaled to said crank shaft, A, by means of the bearings, B and also to said bar, B and must adapt itself to the movements of the crank of said crank shaft and said bar as will be hereinafter described. The rear section, B,

of said shovel rests between the rearward extensions, -B of the forward section and is immovably secured to said bar, B and the forward portion of said rear section rests loosely within the rear portion of said forward section, B, so that, by the rotation of the'bar, B contra-clockwise, as viewed in Fig. 1, said-section, B, may turn or tilt with said bar (on an axis which is horizontal and transverse. to the length of the machine), the forward end of said section being lifted out of the section, B

The movement of the forward portion or nose of the shovel section, B, is controlled by the crank shaft, A. Said crank shaft is rotated contra-clockwise as viewed in Fig. 1, or in the direction of the arrow shown in said figure. .The inoi'enicnt. of the rear end of said forward shovel section is controlled by the cam grooves, A, the transverse bar, B as above described, sliding in said grooves; Hence it will be observed'that the nose of said" forward shovel section will travel-in a,.relatively large orbit while its reai end merely reciprocates in a path which is nearly straight and approximately horizontal. Inother words, said forward shovel section lS--111OVd nearly like an ordinary pitnian attached to an ordinary crank, the movement in'th'e present case being modified by the irregularity of the cam grooves. And

said forward section turns or tilts (not so far as the rear section) on the bar, B or on an axis whiclris horizontal and transverse to the length of the machine.

When during its descent, the nose of the shovel reaches the floor, it is desirable that said nose move forward horizontally or in a plane parallel'to the floor until the forward section of the scoop is filled with the unitei'ial to be loaded. This parallel or horizontal movement of said nose is attained by lowering the rear end of the shovel ,during the interval of forward movement needed for the filling of said forward section. buch lowering of the rear end of the shovel is attained by lowering orinclining theportion. of the cam groove, A, which is forward of. the bar, B when the nose of the shovel reaches the floor, and continuing such in; clination as far as said bar has to travel before said forward-sectionof the shovel begins to lift its load. The load thus taken by the forward section of the shovel is to be transferred from said section into the rear shovel section, and then transferred by the latter to the forward endless apron carrier, (J. For making such transfer of said load from the forward shovel section to the rear shovel section, the shovel is tilted, the nose rising higher and higher while the rear portion remains at approximately the same level. The nose of the shovel is to be thus raised sufficiently to cause its load to slide rearward and downward into the rear shovel section. Said position is attained when the crank shaft, A, is in the position shown bydotted lines in Fig. 1, the bar, B, then resting in the lowest portion of the cam grooves, A. The load being now in the rear shovel section, the further movement of the crank shaft moves the entire shovel rearward until the cranks, B, enter the groove, A. b'aid cranks are keyed on the bar or shaft, B, at each side of the shovel between the extensions, B of the forward shovelsection and the cam plate, A, and extend forward and upward at an angle of approximately fortylive degrees when the shovel is in its lowest position, as shown in Fig. 1 By the time the crank shaft, A, has raised the forward portion of the shovel as high as it will go, said cranks are directed rearward and Up ward, as shown by the dotted lines in the expanded portion of the groove, A, ofthe cani plate, 4 in Fig. 1, the wrist, B on each .of said cranks, B, entering the wide portion of the groove, A. Upon the fun thcr rearward movement of the bar, B, by the further rotation of the crank, A, said wrists of said crank, B, are forced rearward and lo\\-'ii.ward in said groove, A, whereby litt amass the rear shovel section revolves partially around the bar B contra-clockwise as viewed in Fig. 1, until it becomes inverted to such extent as to discharge its lead by gravity. Butthe rapidity of such movement of the rear shovel section may be varied by varying the positions and curves of 'the grooves, A and A and by varying the length of the cranks, B. If so desired such movement may be madesufliciently rapid to cause the throwin rearward instead of permitting it to slide off said shovel section by gravity. \Vhen the" crank shaft, A, has turned rearward to its limit, said forward shovel section and said bar, B cease rearward movement and begin a .forward'movement, whereby the cranks, B reverse their movement and cause a reverse turning movement of the bar, B, and such reverse movement of said ba'r causes the rear shovel section to revolve in the forward direction until said cranks are disen This occurs well down toward the floor and the rear shovel section has to turn approximately sixtydegrees to attain its normal position of rest in the forward section. .Through such arc. said rear section falls by gravity.

The crank shaft, A, is driven by two sprocket chains, D one surrounding each sprocket wheel, A", and a sprocket wheel, 1'), on a horizontal transverse shaft, D, resting in bearings, D and power is transmitted to said shaft, 1), by means of a bevel gear, I), which is mounted on a shaft, 1),

and meshes with a bevel gear, I)*, mounted -on the shaft, D

While the two sections, B and B may be regarded as together constituting a shovel, as they have been above described, the forward section, B", may be by itself regarded as the shovel while the rear section, B, is regarded as a receptacle or receiver, the function of which is to'take the material from the shovel proper and carry it rearward and discharge it upon the apron carrier, C.

In Figs. 7 and 8, the front and rear shovel sections are merged into a single section, B, of approximately the size of said two sections, and a stirrup-like frame comprising a transverse piece, B secured to the crank,

JV, and rearward exensions, B3 corre s ending to the rearward extensions, 1}, of tile previous form, constitutes a rest for .the forward portion of said shovel, the rear portion ofthis second form being securedv to the bar, B, ,to which the rear section of the prestead plates, 13, bearing at their upper endsa lateral wrist, Bf,'are sccured to each side wall of of said load forcibly 'cedingform is secured. And in this modi- -fied form, the cranks, B are omitted from the said bar, B and m the r which is a side elevation, one of the plates, B, stands behind the other. But it is to be observed that, theoretically, one of these plates is sufficient for the turning of the shovel; but for strength and durability, two such plates should be used.
